Please give us an “I’m-feeling-lucky” checkbox for lenses. I’ve already specified my favorite online dictionaries, in order of preference, and I always click the top result. Same with movie reviews, etc. This would save me many clicks.
This carries a functionality you already provide in the search bar (invoked by a single ‘!’, I believe), and allows us to use it in the highly customizable lenses where it would be extremely useful.
